摘要 以凹凸棒黏土(ATP)为原料,Fe(NO33·9H2O为铁源,通过溶剂热合成法制备了Fe3O4纳米粒子/凹凸棒土可磁分离复合材料(MATP),并通过XRD、FE-SEM、TEM、XPS、比表面/孔隙度分析仪及VSM对其进行表征。结果表明,MATP由平均直径约为11 nm的Fe3O4纳米粒子均匀负载于ATP表面而形成;MATP保持了黏土的纳米棒状和多孔结构,比表面积为180.98 m2/g,平均孔径为17.05 nm;MATP具有超顺磁性,饱和磁强度为13.44 emu/g,该特性有助于复合黏土材料从体系中分离及回收再利用。

Abstract: The magnetically separable composite Fe3O4 nanoparticles/attapulgite (MATP) is prepared by solvothermal method using Fe(NO3)3·9H2O as iron source and attapulgite (ATP) as starting material.The prepared MATP is characterized by XRD,FE-SEM,TEM,XPS,specific surface area/pore size analyzer and VSM.The results show that MATP is formed through the Fe3O4 nanoparticles with an average diameter of 11 nm dispersing quite uniformly over the surface of ATP.Meanwhile,MATP retains the nanorod and porous structure of clay,and has a specific surface area and average pore diameter of 180.98 m2·g-1 and 17.05 nm,respectively.Further study demonstrates that MATP is of superparamagnetism with a saturated magnetization of 13.44 emu·g-1,which helps composite clay materials to be separated from system as well as be recovered for recycle.
